摘要：

The reactions of Mn2(CO)9NCMe (1) with the alkynes MeC = CX (X = OEt, NMe2) have yielded the substituted bridging vinylidene complexes Mn2(CO)8[mu-C = C(Me)C = O(X)] (2a, X = OEt; 2b, X = NMe2) in 39% and 10% yields, respectively, by a rearrangement of the alkyne accompanied by a CO insertion. Compound 2b also adds 1 equiv of MeC = CNMe2 to form the complex Mn2(CO)7[mu-CC(Me)C(NMe2)C(Me)C = O(NMe2)] (3) in 50% yield, which contains a four-membered carbocyclic ring.
